Any time you see medical recommendations, estimates of benefits, or lists of potential side effects, these are based on analyzing the reactions of large groups of people in scientific studies. Individual reactions will vary. We recommend repeating Botox after 3 to 4 months because that is the time at which most people tend to notice their results diminishing. If your muscles are very active, you may find your effects wearing off sooner. If you need more Botox, feel free to get it. It's perfectly safe to have another treatment before the 3-month mark. Please consult a board-certified dermatologist who is an experienced Botox injector so that you can be assured you are being treated correctly and with the proper strength of Botox.
Thank you for your question. Botox and other neuromodulators will typically last 3-4 months before they fully dissipate from the injected muscles. I will usually counsel my patients that this is a good time for another dose, if they wish to maintain their results. We will also see our patients back at 2 weeks after injection, in case a touch-up needs to done. These are general guidelines and sometimes an additional dose may need to be given before 3-4 months. I would consult with a board certified injector for a full evaluation. I hope that this helps!-David Gilpin
